AN5768
TILT correction IC
s
Overview
The AN5768 is a rotation correction (TILT) IC for
CRT monitor incorporating a driving transistor. It enables
250 mA (max.) DC current flow by connecting a coil
between the output pins which operate with a reverse
phase each other.

2. Pay attention to an electrostatic breakdown for pin 1.
3. Observe the following sequence of the supply power start-up:
Turn-on sequence
First: Pin 2 on (7 V) power supply
Second: Pin 1 on (12 V) power supply
Turn-off sequence
First: Pin 1 off (12 V) power supply
Second: Pin 2 off (7 V) power supply
